Your system is very close to the two I'm about to build. Question... Have you seen an obvious difference running CS4 with 12GB of RAM?
I'm hoping it will make a big difference for us. Our current Q6600 systems are sluggish and I get tired of hearing the Mac heads in our office bash the Premiere CS4 suite.
Yes i have noticed an improvement. I can now run multiple CS4 apps without the system choking up or running out of ram and the system appears to be more stable. The increase in performance from the old system is nice too.
I'm also running vista x64.
Nados: Glad you figured it out and got everything running now! Congrats.
Charles and Nados: I you both could run the http://ppbm4.com benchmark and send your results to Bill, it will give an indication of how your system is performing. Interesting would be to see the results of Jim Simon, since he is running with 3 GB of memory on an i7-920 and most here are running with 12 GB, so the differences may be telling what performance gain you can expect from the extra memory. For you Charles, it is interesting to see your current system in comparison to the one Nados now has. It will show you what the new system has in store for you.
I started out with 12 GB so I can't tell what the performance gain is of 12 over 6 GB.
